摘要：热处理选取了5个温度(170、185、200、215、230℃)和4个时间(2、4、6、8 h)。在热处理前后分别测量蓝变点与未蓝变点的颜色,分析了蓝变材颜色的均匀性,对比了蓝变点与未蓝变点的颜色差异和变化规律。实验结果表明:热处理后,蓝变材颜色参数的标准差逐渐降低,蓝变点与未蓝变点明度差、黄蓝色品指数差减小,其色差可以从17.57降低到小于1。均值比较结果显示,经过200℃以下的热处理,蓝变点与未蓝变点间的颜色参数仍然具有显著性差异。为了使蓝变色斑达到肉眼不容易识别的程度,最低的热处理条件为200℃下处理6 h。
We established satisfactory heat treatment conditions for blue-stained masson pine by evaluating the effect of heat treatment on wood color. Heat treatments were conducted under five temperature levels of 170,185,200,215 and 230℃） and four duration levels（2,4,6 and 8 h）. We measured wood color of both stained and unstained area before and after heat treatment,analyzed the color homogeneity of blue-stained wood,and studied the plus color evolution and color differences between stained and unstained area. After heat treatment,standard deviations of wood color parameters of bluestained area reduced,the differences in lightness,chromaticity coordinates decreased,and total color difference between stained and unstained area reduced from 1 to 17. 57. By mean comparison,treatments under 200 ℃ hardly improved the color homogeneity of blue-stained wood. The minimum treatment intensity should be 200 ℃ for 6 h to make blue stains invisible.
